I have been asking the same thing. One reply was to use VBA to activate the
function. Unfortunately I don't know how to implement it. If you do, look
back a few posts which will give you the line of code.
If you customise the mini bar, you can find an inbuilt email function called
"send to email recipient". With my system, it crashes Word. Other functions
have been disabled from earlier versions like signatures & stationary unless
you have outlook. So much for the upgrade.
